Bojan Pancevski & Jared S. Hopkins (2020-10-22): How Pfizer Partner BioNTech Became a Leader in Coronavirus Vaccine Race https://www.wsj.com/articles/how-pfizer-partner-biontech-became-a-leader-in-coronavirus-vaccine-race-11603359015: ‘MAINZ, Germany—On a Friday in late January, Ugur Sahin received an email with bad news: A new study of a deadly new coronavirus in China suggested it was more infectious than previously believed. The outbreak, he believed, had the potential to grow into a pandemic. The following Monday, the German scientist and chief executive of biotech firm BioNTech SE summoned his board to announce that the company, which had been developing next-generation cancer treatments, would start work on a Covid-19 vaccine. Human trials would need to start by April, he added, in case Europe and the U.S. had to go into lockdowns. Ugur Sahin, co-founder and chief executive of BioNTech, led the company to focus on coronavirus research early in the pandemic. While much of the world was still oblivious to the danger, BioNTech was scrambling, Dr. Sahin told The Wall Street Journal earlier this month…

BioNTech: '“Our vaccine consists of a short segment of… messenger RNA… provid[ing] instructions for a human cell to make a harmless version of a target protein,… which activates the body’s immune response against the SARS-CoV-2 virus. We expect that our vaccination approach will stimulate the immune system to generate protective antibodies. This means the immune systems learns how to recognize the SARS-CoV-2 virus upon exposure and prevent subsequent infection. Unlike other vaccines, mRNA vaccines do not contain the virus itself and therefore pose no risk of infection…
